In a New York Times op-ed titled “The Decline of Unions and the Rise of Trump,” Dana Professor of Sociology Neil Gross explores why unions are not as effective at pushing their members to “overcome prejudices bearing on politics” as they have been historically. Gross asks why unions haven’t “been able to tamp down the appeal of Mr. Trump” in his Aug. 12 article. One reason, he writes, is that “unions have been profoundly weakened by changes in the American economic structure, and by decades of assaults against them by the Republican Party.”
